I'm trying to send SysEx messages from my MIDI controller to OSCII-bot, but I don't know how to achieve this.
As indicated in the reference code, in case of receiving SysEx the variables 'msg1', 'msg2' and 'msg'3 are equal to 0, and the SysEx message is stored in string format in 'oscstr'.

But how can I extract the info from oscstr byte by byte? This is what I need to "decode" the info inside the SysEx packet.

Search the forums for posts/threads by user "fundorin". Other forum users offered advice to him on the topic of byte handling and how to use EEL2 language for this on integrating a Novation keyboard/controller.
